Black & white '60s TV episode; A young man, dark hair, wearing khakis & a plaid shirt(?) is in town when he hurts himself, cutting his arm/wrist open, only he doesn't bleed. Instead he sees wires inside his arm, and ends up finding his way to the basement laboratory where he was made, eventually discovering he is not human, but a robot.
I thought the actor was George Maharis (not). I thought it was a Twilight Zone episode or The Outer Limits (not). It was definitely a short (30 minute) episode of some syndicated show very much like TZ. Any help would be appreciated.
